I'll bet you have a bad spark plug wire end.  Itis probably shorted to the
metal shield.  Try another wire and see if that resolves the problem.  If
not, try swapping the injector with another cylinder to see if the problem
goes with it.  These injectors do not vapor lock.  The very rarely clog.
 Hope this helps,
